Wales

Wales was a location which existed in multiple universes. It was part of the United Kingdom, and its residents, the Welsh, were therefore British — but not, contrary to popular belief among foreigners, English.

In the home universe of Jenny Over-There, the original M.F.S. office was located in Wales, with a later branch in Scotland. (PROSE: Open Sourcing) The Over-There family home itself was also “nested in the middle of one of the more urban areas in Wales”, though she did have to drive to get from one to the other. (PROSE: A Very Jenny Over-There Christmas)

Dynamite Thor, after moving there, confessed to Jenny that he'd never been to Wales in his original universe, suggesting it also existed there. (PROSE: A Series of Queer Events)

In Reality Z-25 31-H, Kate Five was Welsh, (COMIC: Kate Five vs Symbiote - Chapter 2) with the headquarters of her superhero team Section P being in Cardiff. (COMIC: Kate Five vs Symbiote - Chapter 1)
